+Makefile: do not force the release build on install
+
+If we did build any of the other targets, and are just interested
+in those and not the release one, we still want to use the 'install'
+rule, but not build (and install) the release libraries.
+
+So, remove the dependency on the 'release' target from the 'install'
+rule.
